My daughter is 10, yesterday she had what looked like a simple heat rash on the inside of both her feet, today she has clusters of tiny little blisters not only where the rash was but on and in between her toes as well. I have not seen this before. I have heard and seen hand foot or hoof and mouth disease, and this does not look like it. She is also not feeling well. She just feels not right her stomach kinda hurts, but she has not lost her appetite nor does she have a fever, however she does look a little flushed, but she did get some sun this weekend as well. If you can please give me your opinion on what this is, and what action to take I would greatly appreciate it. She does have a Dr. appointment next week. Should I take her in sooner? Thank you for your time:)
